VIBRATOR.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed February 1l, 1907. Serial No. 356,902.

To all whom it may concern:

Be it known that I, CHARLES ROBERT ELLIOTT, a citizen of the UnitedStates, residing at Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in Vibrators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. l

This invention relates to improvements in electric vibrators, or massagemachines.

The object of the invention is to provide a machine of this character bymeans of which vibrations are produced by the unbalanced armature of themotor therein.

The further object of the invention is to provide a handle for themachine so constructed as to absorb and prevent the vibrations of themachine from being conveyed to the hand of the operator, thus enablingthe device to be more easily held and applied to a patient.

With the foregoing and other objects in view, the invention consists inconstruction, combination and ar rangement of devices hereinafterdescribed and claimed.

In the accompanying drawings Figure l is a side view of the vibratorconstructed in accordance with the invention, Fig. 2 is a similar viewof the body-portion and operating parts of the machine, with a part ofthe casing removed; Fig. 3 is a detail view of the armature removed fromthe motor, and Fig. 4 is a similar view of the armature showing anunbalanced ily-wheel mounted thereon to produce vibrations in themachine. Fig. 5 is a detail side view of an armature, the shaft of whichis provided on its opposite ends with eccentric or offset journals.

Referring more particularly to the drawings, l denotes the body-portion,or casing of the machine, which may be of any suitable shape, and whichis here shown, and is preferably, in the form of an oblate spheroid.Arranged within the casing, l, is a motor, 2, the field magnets of whichare secured to the casing7 and within the field is adapted to rotate anarmature, 3.

The construction of the armature, 3, is such that the same will beheavier at one side so that when running the same will be unbalanced.The unbalancing of the armature may be produced in a number of differentways, such, for instance, as increasing the size of one of thepole-pieces, or by increasing the wiring on one of the poles, or, asshown in the present instance, by providing a weight, 4f, and securingthe same to the armature shaft, between two of the pole-pieces. Theunbalancing of the armature may also be produced by mounting anunbalanced ffy-wheel, 6, on the end of the armature shaft, as shown inFig. 4 of the drawings, or by providing the armature shaft witheccentric or offset journals, 9, at its opposite ends as shown in Fig.5. The same effect would also be produced by a bent or sprung armatureshaft. By providing the unbalanced armature, the body of the machinewill be caused to vibrate when the armature is revolved therein, saidvibrations of the body-portion of the machine being conveyed ortransferred to the patient by means of a suitable applicator, such asshown at 7.

Attached to the body-portion of the machine is a flexible handle, 8,said handle being here shown, and is preferably, in the form of a coiledwire, the coils of the same being larger near the outer end to provide asuitably shaped handle, which may be conveniently grasped by theoperator, there being formed at the forward end of the handle an eye 9designed to receive the screw bolt lO, by means of which the handle isattached to the casing l. By providing the exible, coiled wire handle,S, the vibrations of the body-portion of the machine will be partlyabsorbed, thereby relieving the hand of the operator from the full forceof the vibrations, thus enabling the machine to be more readily held andcontrolled when being applied to the patient. The coiled wire handle, S,also provides a convenient receptacle for the ends of the electricconducting wires 1l and 12, which are adapted to pass therethrough thewire 1l being carried through the casing to the motor, while the wire 12is terminally engaged with the screw l0, by means of which it isattached to the casing. Thus it will be seen that the screw subservesthe functions not only as a fastening means for the handle, but also asa binding post for the wire l2 while the eye 9 acts as a clamping washerbetween which and the wall of the casing the wire is clamped.

The machine may be operated by batteries or any other source ofelectrical supply.

In a vibrator constructed as shown and described, the applicator may bepressed as forcibly as desired against the body of the patient withoutinterfering with the operation of the machine, or requiring any morepower.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring more extended explanation.

Various changes in the form, proportion, and minor details ofconstruction may be resorted to without departing from the principle, orsacrificing any of the advantages of this invention, as defined in theappended claims.

Having thus fully described my invention what I clamped on saidfastening bolt between the eye and wall of the casing. 1.0
